1" RAM Ball Socket to AMPS Adapter

This adapter incorporates a standard 1" (25.4 mm) compression socket with an AMPS 30 × 38 mm mounting pattern , allowing you to mount RAM® B-size compatible accessories to any AMPS-compatible base or device.

Compatible with most 1" ball systems (RAM Mounts, Arkon, Tackform, Bulletpoint, 67 Designs, iBolt, Lido, Panavise, ProClip, Brodit, Quad Lock 1" Ball Adapter, and other RAM-compatible products).

The AMPS hole pattern is widely used on GPS cradles, tablet mounts, vehicle docks, marine electronics, radio mounts, industrial equipment, and many aftermarket mounting systems.

The print profile has a version with nut insets/traps and another version without nut insets/traps.  I have not needed supports.

It seems quite strong, even though printed vertically.  Also, given the nature of the swivel connection, there usually isn't much lateral torque on anything.
